I accidentally deleted a computer object from active directory.  Is there an easy way to re-create this computer object.  I know the computer name and IP.  I no longer can log into that system because of my error.  I had thought to sign in locally and remove it and then add it to the domain again, but I cannot login locally either.  Any help would be appreciated.

You're on the right track; yes, you should be able to logon with a local account, remove it from the domain, and add it again. Try to remember the password of this account.
If you don't, you can try to unplug the machine from the network and logon again with an administrative domain account that has logged on to that machine before; I'm not completely sure if cached credentials still work after a logon request has been denied.
If you manage to logon this way, the first thing to do is to RESET THE PASSWORD of the local administrator account to a known value; logoff, log on with the local account, proceed as planned.
Other than that, you'll have to reset the password; check, for example, http://www.petri.co.il/forgot_administrator_password.htm

I unplugged it from the network, rebooted and the system allowed me to login.  as you were saying, the system may have had the login credentials stored in cache... and you were right. Great job and thanks!
